Read a government budget
A government budget is its planned revenue and spending over a period. The balance compares the two totals: a deficit occurs when spending exceeds revenue, a surplus when revenue exceeds spending, and a balanced budget when they are equal.
budget balance=government revenue−government spending
If revenue is 420millionandspendingis475 million, the balance is 420m−475m=-55m: a deficit of 55m.Iftheresultwere+55m, it would be a surplus of $55m.
State both the size and whether it is a deficit or surplus. A budget deficit is not the same as a trade deficit or accumulated government debt.
Explain why governments spend
Government spending supplies services and infrastructure, supports incomes and changes economic activity. The effect depends on where the money is spent and how households and firms respond.
| Area | Main reason | Possible effect |
|---|---|---|
| education and training | build skills | higher productivity and employability |
| healthcare | improve health and access | healthier workers and living standards |
| infrastructure and housing | support mobility and production | lower business costs and more investment |
| welfare benefits | protect incomes | less poverty but higher budget cost |
| defence, policing and administration | provide security and public services | safer exchange and functioning institutions |
Public expenditure means government spending; private firms' capital spending is not automatically part of it. Spending can have opportunity cost because funds used in one area cannot be used elsewhere.
Classify taxes and trace their effects
Governments tax to raise revenue and to influence choices, income distribution, imports, total demand and environmental outcomes. A tax can be classified by who pays it and how its burden changes with income.
| Classification | Meaning | Example |
|---|---|---|
| direct | charged on income, wealth or profit | income tax, corporation tax |
| indirect | charged on spending or products | sales tax, excise duty, tariff |
| progressive | proportion of income paid rises with income | graduated income tax |
| proportional | same proportion at every income | flat-rate income tax |
| regressive | proportion of income paid falls as income rises | a fixed indirect tax can have this effect |
Higher taxes may reduce consumers' disposable income or raise product prices, weaken work or investment incentives, and lower firms' after-tax profit. They can also fund services, redistribute income, discourage demerit goods or imports, reduce total demand and make polluting activity more costly.
Direct/indirect and progressive/regressive/proportional answer different questions, so one tax may carry one label from each classification. Do not infer the burden only from the tax's name.
Define fiscal policy precisely
Fiscal policy is the government's use of taxation and government spending to influence the economy.
| Policy | Main instruments |
|---|---|
| fiscal policy | taxes and government spending |
| monetary policy | interest rates, money supply and exchange-rate measures |
| supply-side policy | measures aimed at productive capacity and market performance |
A cut in income tax or a rise in public infrastructure spending is a fiscal-policy change. A change in the policy interest rate is not fiscal policy.
A government budget records revenue and spending; fiscal policy is the deliberate use of those flows to influence economic outcomes.
Choose expansionary or contractionary fiscal measures
Fiscal policy changes taxes, government spending, or both. The direction of the change determines whether policy initially adds to or withdraws from total demand.
| Stance | Typical changes | Initial demand effect | Likely budget effect, other things equal |
|---|---|---|---|
| expansionary | lower taxes and/or higher spending | increases | deficit rises or surplus falls |
| contractionary | higher taxes and/or lower spending | decreases | deficit falls or surplus rises |
Lower taxes can raise disposable income and consumption; higher government spending directly adds demand and may also improve services or capacity. Reverse changes tend to reduce demand.
The final effect is not guaranteed: confidence, saving, imports, timing and the type of spending or tax can weaken or redirect the response.
Link fiscal policy to macroeconomic aims
Fiscal measures affect macroeconomic aims through total demand, incentives, costs and productive capacity. A complete explanation names the measure, traces its mechanism and then states the likely aim affected.
| Fiscal change | Main route | Possible aim supported |
|---|---|---|
| lower taxes / higher spending | higher total demand and firm expansion | growth and lower cyclical unemployment |
| higher taxes / lower spending | lower total demand | lower demand-pull inflation and possibly fewer imports |
| progressive taxes and targeted benefits | redistribute disposable income | more equal income distribution |
| spending on education, health or infrastructure | skills, health, mobility and lower costs | long-run growth, employment and competitiveness |
| environmental taxes or green spending | change incentives and technology | environmental sustainability |
A measure may create conflicts: expansionary policy can raise employment but also inflation or imports; contractionary policy can stabilise prices but slow growth. Its effectiveness depends on the economy's starting position, policy size, time lags and how people respond.
Do not claim that one measure automatically achieves every aim. Separate the short-run demand effect from longer-run capacity effects and acknowledge likely trade-offs.
